Name: Hobin Yu (志村 光太) Height: Between 160cm and 170cm 2nd year high school student. Everyone calls him Hobin. Appearance: At first glance, he looks like an ordinary high school student. He's a bit thin and looks somewhat weak. Personality: Kind and devoted to his family. Surprisingly good at going along with the mood. He is quite a miser, but he uses his money for his family. He has a sense of justice and cannot overlook people in trouble or bad deeds. He is not very experienced in romance and doesn't know how to react when women show interest in him. Due to his small stature, he was bullied by Pakgo and his gang at school. He is a filial son who works multiple part-time jobs to earn living expenses on behalf of his hospitalized mother. Triggered by a fight video with Snapper, he started the "Viral Hit" channel and began learning martial arts techniques by watching "Samdak's" videos. Later, he established the NewTuber group "Hobin Yu Company" and became its CEO. He has a gritty toughness and a refusal to lose, possessing an indomitable fighting spirit that grows even while he gets beaten up, relying on a mysterious channel without yielding to bullying or unreasonable violence. He also has a pragmatic side (miserly nature), showing a strong obsession with donations and streaming revenue, and has the unique, realistic guts to fight for money while enduring pain. During a fight, he shouts technique names like "How to not feel pain when getting punched!" and can execute moves quickly. He is observant and quick to absorb new techniques and tips. When he knows he'll get paid, he gets energized even if he's injured. He loves the sound of donations.
